Description

  The present invention relates to, for example, a fence attached to a column that is erected on a top surface of a parapet or base via a column anchor.

In general, the fence is supported by a column made of aluminum hollow material having a rectangular cross section for aesthetics and rust prevention, but because it is made of aluminum, it tends to be insufficient in strength. A flat pedestal is welded to the lower end of a stainless steel or other steel pillar anchor, and the pedestal is secured to the upper surface of a parapet or base (hereinafter referred to as a base) with screws or the like. Pass through the hole formed in the headboard, fix the headboard to the base, place the column anchor in the column, screw the screw into the screw hole formed in the column anchor from the outside of the column and fix the column It is fixed to the column anchor.
nothing special

However, since the conventional pillar anchor has a relatively short length, the pillar reinforcing effect is not sufficient, and the pillar may be plastically deformed by wind force or a human load applied to the fence body.
Further, although the column anchors are rust-proofed, conventionally, since a tapping screw is screwed into the column anchors in the field, there has been a problem that rust is generated in the screw holes of the column anchors.

  The present invention has been made in view of the above points, and the problem to be solved is that the reinforcing effect on the support is increased by a simple structure, the rust prevention performance is excellent, and the support can be easily fixed. The object is to provide a rail with a prop anchor.

  In order to solve the above-mentioned problems, the present invention provides a fence attached to a column that is erected via a column anchor, the column anchor being a steel hollow material that is housed in the column, and a lower end portion of the hollow material. It comprises a base that is welded and fixed to the upper surface of the base, and a plate-like aluminum screw receiving member that is fixed in the hollow material. The screw receiving member is fixed to the inner wall surface of the hollow material, closes the vertically long hole, and has a screw penetrating the support column. It is screwed through the vertically long hole to fix the column.

  In the above configuration, the hollow material of the pillar anchor is made of steel and is housed in the pillar. Therefore, since the support is reinforced, plastic deformation of the support is prevented. A screw receiving member is fixed to the hollow material of the post anchor after the rust prevention treatment. Therefore, rust does not occur in the pillar anchor. Since the screw for fixing the column is screwed into the screw receiving member facing the vertically long hole of the column anchor, rust is not generated due to screwing of the screw, and the screwing resistance is small. Therefore, the column can be easily fixed to the column anchor.

  According to the present invention, since the hollow material of the pillar anchor is made of steel and is housed and fixed in the pillar, it has a large reinforcing performance with respect to the pillar, so that plastic deformation of the pillar is prevented. Also, a screw receiving member that closes the longitudinal hole is fixed to the post anchor after the rust prevention treatment, and the post is fixed by screwing the screw into the screw receiving member through the longitudinal hole from the outside. This effectively prevents rusting. Furthermore, since the screw for fixing the column is screwed into the screw receiving member facing the vertically long hole of the column anchor, there is little screwing resistance and the column can be fixed easily.

Next, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of an example of a fence supported by a column that is erected using a column anchor, FIG. 2 is a diagram illustrating an example of a column anchor that is a main part of the present invention, and FIG. (B) is a plan view. FIGS. 3 to 8 show a process of erecting a support using the support anchor of FIG. 2, FIG. 3 is a perspective view showing a first process and a second process of erecting the support, and FIG. FIG. 5 is a perspective view showing the fourth step, FIG. 6 is a perspective view showing the fifth step, and FIG. 7 is a perspective view showing the sixth step. FIG. 8 is a view showing a column base for waterproofing and drainage of the lower end of the column, (a) is a perspective view of the top surface, and (b) is a bottom view. 9 is a longitudinal sectional view showing a state at the end of the sixth step, and FIG. 10 is a sectional view taken along line XX of FIG.

  In FIG. 1, F is a fence, 1 is a base, 2 is a cap fixed to the upper surface of the base, 3 is a support fixed to the upper surface of the base, and is erected through the cap, 4 is an upper end of the support A handrail fixed to 5 is a panel as an example of a fence body attached between the columns.

  In order to erect the column 3 shown in FIG. 1, a column anchor 6 shown in FIG. 2 is used. The column anchor 6 is constructed by welding 63 a lower end portion of a stainless steel or other steel hollow material 61 having a rectangular cross-sectional shape to the center of a steel plate base 62 having a rectangular flat plate shape. The hollow member 61 has a length close to the length of the pillar of the fence, and at least both longitudinal ends have longitudinal elongated holes 61a, and screw holes 61b are formed in the vicinity of each longitudinal middle hole. The pedestal 62 of the column anchor 6 is formed with a drain hole 62a at the center and a long hole 62b near the four corners. The support anchor 6 is subjected to rust prevention treatment such as plating in a state where the hollow material 61 and the pedestal 62 are welded.

An aluminum strip-shaped screw receiving member 7 is provided on the inner surface of the wall in which the elongated hole 61a of the hollow material 61 of the column anchor 6 is formed, and the column anchor hollow material 61 is screwed by a screw 8a screwed from the screw hole 61b. The both ends of the screw receiving member 7 close the vertically long hole 61 a of the hollow material 61. Since the screw 8a is screwed into the column anchor 6 subjected to the rust prevention treatment, the screwing of the screw is prevented from causing rust.
In the illustrated example, the screw receiving member 7 is made of one long material, but a plurality of members made of a short material corresponding to each vertical hole may be used.

Next, a procedure for erecting the column 3 using the column anchor having the above configuration will be described with reference to FIGS. 3 to 7.
As a first step, as shown in FIG. 3, a column anchor is fixed to the upper surface of the base 1. As shown in FIG. 3, the column anchor 6 having the screw receiving member 7 on the inside has a pedestal 62 placed on the upper surface of the base 1 with the vertically long hole 61a facing the inside of a fence such as a balcony or a fence. The coach screw 8b is screwed into the base 1 from the long hole 62b. The lengths of the pillar anchor 6 and the screw receiving member 7 are determined according to the height of the handrail 4, that is, the height of the pillar 3, but are close to the height of the pillar so that the greatest reinforcing effect can be obtained. The length is, for example, about 800 to 1300 mm.

  Subsequently, as shown in FIG. 3, as a second step, the headboard 2 is lowered from above the base 1, and the hollow material of the pillar anchor 6 is inserted into the hole 21 having a shape similar to the cross-sectional shape of the pillar anchor formed in the headboard. As shown in FIG. 4, 61 is inserted, and the cap is adjacent to the upper surface of the base 1 and is elastically fitted and fixed to a known holder (not shown). In this state, as shown in FIG. 4, the column anchor 6 stands upward from the hole 21 of the headboard 2. At this time, there are many cases where a slight gap is generated between the outer peripheral surface of the hollow member 61 of the support anchor 6 and the periphery of the hole 21 of the headboard 2.

  Therefore, as a third step, as shown in FIGS. 4 and 5, a sealer 9 is provided on the upper surface of the headboard along the gap to close the gap. The sealer 9 is formed by cutting two sealer members formed in an L shape from a synthetic rubber or plastic material into lengths that match the widths of two adjacent side surfaces of the hollow material 61 of the column anchor 6, and separating them. It arrange | positions in the reverse symmetrical form on the mutually opposite side of the anchor 6, and it continues in a rectangle and seals a clearance gap. The sealer 9 can also be formed as a single rectangular ring. However, in that case, it will be dedicated to the pillar anchor of a predetermined size, and it is troublesome to fit it from the upper end of the pillar anchor and pull it down to the top of the headboard of the base so that it is troublesome. In addition, if an L-shaped sealer member is made and cut and used in accordance with the dimensions of the pillar anchor, it can be applied to the pillar anchors of various dimensions with one kind of sealer member, so that the manufacturing cost can be reduced.

  Next, as shown in FIGS. 5 and 6, as shown in FIGS. 5 and 6, the column base 10 is inserted into the hollow material 61 of the support anchor 6 from above and placed on the upper surface of the headboard 2 to accommodate the sealer 9. Then, the sealing material 11 is filled and the space between the column base 10 and the outer peripheral surface of the hollow material 61 of the column anchor 6 is sealed and fixed. More specifically, as shown in FIG. 7, the column base 10 has a rectangular annular frame portion 101 having the same shape as the cross-sectional shape of the hollow material 61 of the column anchor 6. The frame portion 101 has a flat surface on the upper surface and has an inner peripheral wall 102 that rises continuously in a rectangular shape along the inner periphery. And it has the convex parts 103 and 104 which protrude mutually opposite in the height direction middle of the inner peripheral surface of the inner peripheral wall 102. A space for accommodating the sealer 9 is formed in a portion surrounded by the inner peripheral surface of the inner peripheral wall 102 below the convex portions 103 and 104, and the inner peripheral wall 102 above the convex portions 103 and 104 is formed. A sealing material filling space, which will be described later, is formed in a portion surrounded by the peripheral surface. Therefore, the size of the inner peripheral surface of the frame portion 101 is substantially matched with the outer dimension of the sealer 9. Further, a drainage groove 105 that opens to the upper surface is formed on one opposite side of the frame portion 101 at a position close to the inner peripheral wall, and the drainage groove 105 opens laterally on one of the other opposite sides of the frame portion. Has been.

  Thus, as shown in FIG. 6, the hollow material 61 of the column anchor 6 is inserted into the inside of the frame portion 101 of the column base 10, and the side opening of the drainage groove 105 is directed toward the inside of the balcony or the inside of the fence. When the frame portion 101 is placed on the upper surface of the headboard 2, the convex portions 103 and 104 come into contact with the outer surfaces of the hollow material 61 of the column anchor 6, and the column base 10 is positioned at a predetermined position. At that time, the previously installed sealer 9 is accommodated in the sealer accommodating space of the column base 10 and is pressed by the inner peripheral wall 102 and the convex portions 103 and 104. Accordingly, the sealer 9 is fixed without being bonded to the upper surface of the headboard 2 or the like, and the effect of preventing rainwater intrusion between the pillar anchor 6 and the headboard 2 can be obtained by the sealer.

  Further, a sealing material filling space opened upward between the inner peripheral wall 102 on the upper surface of the column base and the hollow material 61 of the column anchor 6 is filled with a sealing material 111 from, for example, the tube 11 or the like. 101 is completely sealed. Therefore, high watertightness is ensured between the lower part of the hollow material 61 of the support anchor 6 and the headboard 2.

  As the last step, as shown in FIGS. 6 and 8, the column 3 made of aluminum hollow material having a rectangular cross section is lowered from above the hollow material 61 of the column anchor 6, and the hollow portion 31 is lowered. The hollow material 61 of the column anchor 6 is inserted into the column 3, the lower end surface of the column 3 is brought into contact with the flat upper surface of the frame portion 101 of the column base 10, and the screw 33 is screwed through the hole 32 formed in the column 3 in advance. . Since the screw 33 is screwed into the screw receiving member 8 facing the vertically long hole 61 of the hollow material 61 of the column anchor 6, the column 3 is firmly and firmly fixed to the column anchor 6.

  The lower end surface of the column 3 is in close contact with the upper surface of the frame part 101 of the column base 10, but the drain groove 105 of the column base is formed at a position lower than the upper surface of the frame unit 101. Rainwater that may enter the water flows down along the inner wall surface of the column 3 and is guided by the sealing material 111 filled in the upper surface of the column base, flows through the drainage groove 105, and enters the balcony or fence from one end thereof. Drained inside.
